I don't know about that particular controller, but the the graphics display controllers I have used have commands for either pixel-specific setting and clearing, or for "and" or "or" on an 8-pixel byte. If not, then it should at least allow reading back from its display memory, so that you can do the "and" or "or" yourself.
